Nexus 10 turning off in sleep mode - Nexus 10 Q&A, Help & Troubleshooting

Hello!
I bought Nexus 10 at nearly two weeks, and since the beginning i have noticed an issue i thought would be Software related. As the device is on idle, everything works pretty well. Watching movies, web surfing, etc. Doesn't matter if it's for 5mins or 5 hours. But when it goes to sleep mode (automatically or forced by me), it just turns off consequently. I would say 90% of the times. An then Nexus just turn back to life after a long power button press, like 10 secs or more.
First i read about some people who have problems caused by autosleep function related with some cases. When i remove my tablet from the Poetic case, it keeps going off.
Then i read about Location services. It's turned off too. Such as the wi-fi in sleep mode. Didn't solve either.
Any idea?
PS: I'm from Portugal and my English is not the best. Sorry about that.

Thanks for the response anyway.
Is that thread about freezing? My Nexus is not freezing.

Hello! Yes, that is one of the threads Im talking about. I found it to hard to find people who posted with as good of detail as you did, so I had to "latch on" to the biggest group that was vocal about their problems. But mine manifests itsself almost always as sleep of death, and NOT reboot - just like yours. Here are some links:
Google: https://groups.google.com/a/googleproductforums.com/d/msg/mobile/-/GFnACv1nC0MJ
On of the XDA: http://forum.xda-developers.com/showthread.php?t=1998496&page=39
As I say on the Google thread:
My thoughts on the error:
1) The most logical explanation I've heard yet is the memory leak that B has been posting about
2) I think this memory leak/problem can manifest its self as crash, reboot, or sleep of death
Right now I am trying Stock 4.2.2, rooted, using KTmanta kernal. This is the second day Im on a non-stock kernal, too early to post any useful info.
Good luck on this,

say, quick question since you are in same boat as me - does your device's serial # start with R32C or R32D?

My device is R32D.
I guess i will call the seller tomorrow and figure out if it's possible to return the tablet. At this point, it's completely unusable.

I agree that the inability of this device to reliably stay powered on is a deal breaker, at least in a work scenario.
I actually bought mine "just for games", but have been really concerned about trying to resolve this issue to verify its not a hardware issue and I miss my warranty period. I cant honestly say I think its a harware issue, so I am really trying to find a ROM/Kernal/settings combo that resolves this.
I have a lot of faith in the dev community for ROMs and kernels, but I think its absolutely scandalous and horrible that I have to click past a warning that says 'may void your warranty' to install softare on my device to make it perform AS IT SHOULD HAVE direct from Google.
If not for all these issues I would have NEVER gone custom recovery, root, and new kernel. Im glad this has forced me to do so because Ive loved finally having a justification for "risking" my expensive device, but again that learning experience is NOT what Google is taking $500 payments for here https://play.google.com/store/devices/details?id=nexus_10_32gb so Google should be SHAMED!
Thanks for the info on your serial number, that actually relieves a concern of mine that somehow the 'newer' units werent having this problem. Mine's a C.

I hope it stays that way for you. It will take a few more days with the device to know for sure. If the problem comes back it'd be worth noting here for troubleshooting. :good:

I called back the seller, and they will do the return. Really bad situation...

i left my n10 in my house and its idle with 41% on battery i just got home and open the device it consume only 1% without random reboots. hope itll stay this way ill root this and install crom maybe nextweek.

So - now I am 2.5 days into testing 4.2.2 OS with a different kernel. And so far, NO sleep of death! AND I've been using the tablet a lot more than my "minimal use" in my other tests! This of course is the ultimate test - I'm posting/talking about it on the internet so certainly if its going to blow up in my face, now would be the time. But as of right now - it looks like the alternate kernal is better for my device than Google's...
I am using the KTmanta kernel.

It is important to note that the issue described in this thread does NOT involve the device turning itself off. Rather the issue is that the device is unresponsive when in sleep mode. You can tell this is the case in a few ways, but two obvious ones are that the notification light continues to function and the device requires a 10-second power button reset (the procedure for forcibly rebooting the device).
Personally, I am on CM10.1 night lies with Ktmanta kernel and still experiencing this problem.
Bigmatty, can you tell me what governor, i/o scheduler and clock settings you are using? Thanks.

Well, the majority of the complaint threads do not specifically or mainly focus on the device turning its self off, but this thread actually does.
My sleep- of- death problem on my old unit persisted on any scheduler/clock settings I tried, and I tried a lot w/ KTmanta. But it was RMA my device to get a new one that fixed my SoD.
Oh, and the LED flashing does not mean the unit is actually on, you can test that by plugging in a charger before attempting a long (power on) press = if you get instant battery charge indicator your unit was actually off.

That's REALLY weird, because based on a number of findings by a number of people, it turns out that this issue is related to a bug in the GPU driver that is causing a massive memory leak. You can check by opening a Terminal Emulator and running the command "ps su" This will show the memory usage for the "surfaceflinger" application, which is where the memory leak manifests. Memory usage should never go above ~70mb for that application, but on the N10 it balloons up above ~300mb before the system locks up.
Apparently we're all waiting on Samsung to fix the problem :\

After my two months of trouble shooting I feel strongly that there are two main issues: memory leak and "something to do with power". Likely a software/driver/OS problem on the memory leak like the majority says. BUT - not everyone has the power problems. I think the power problems are hardware related.
Only a couple other users have talked about experiencing the power problems...
If I was going to place a bet, I'd say based on your description of symptoms you too have the power problem. Ask the others in threads you are following if they have the LED thing, I'm guessing they don't.
Rxnelson on these forms does. He's seen it on two physical units. For me, it didn't appear on my second physical unit.
Good luck!!

"LED thing?" The LED thing is just the notification light continuing to flash even when surfaceflinger has locked the system. Don't really see how that's related to power in any way. The way that LED notification lights work is that the system sends an "on" signal to the LED control chip which then just runs the notification light pattern in a loop until it receives the "off" signal from the system. If you don't have any notifications prior to surfaceflinger going ballistic, or if you have the notification light disabled (many people do) you'd never notice this particular symptom.

Also please note the tip I shared about diagnosing if it's off or on via the charger I posted above, handy trick another user taught me.

Not quite what it seems. If the unit was on, plugging in the charger would not instantly,w/out delay, display the powered off charging indicator.

Ahh, okay, bit of a miscommunication. I'm not referring the power-on notification light. I'm referring to the notification light flashing that occurs when you have a notification waiting (new email, new gTalk message, etc). The charging light is something different, and not what I was referencing
NOTE: This is a function of CyanogenMOD 10.1 that is not present in the stock ROM, I think, so that may be where the confusion lies. Sorry about that

Yes dude, I understand. Just test what I am saying. When I saw my white gmail led flash, but then couldn't turn on I thought the exact same thing you typed. Then while discussing w/power users someone told me to try that. Next time it happened I tried it, was SHOCKED to see what happened, knew I had a problem (that was not just shell reboot.)

My tablet just started doing this as well. It's never done it before, it started about a week ago. What could be causing this? I just factory reset to see if it'll fix the problem. I'll report back in a few days to see if this fixes the issue.

Possible cause and solution to X10 Battery? -"No Sleep Bug"

Hey guys,
Just updated to the x10 after my samsung galaxy died on me, so far i am rather happy - except for the lack of root, but that will come.
I have noticed many complaints on the forum about battery life, and have experienced the same thing myself. From my experience, i think this looks like the same issue that was faced on a leak of 1.6 for the galaxy - it was referred to as the "No Sleep Bug".
TBH, the name says it all - for some reason, in many builds of android 1.6, phones were not sleeping correctly. There are many theories as to why, from cpu not being allowed to sleep, to permanent communication with google servers.
Despite all these different theories, one thing seemed to fix the problem - turning off all location services. Some people argue that a different carrier build, turning off just 'share with google' under location, turning off just AGPS etc. would fix it, but from my experience, the only real way to fix the issue was to turn off all GPS usage unless you need it. The once you have used it, reboot your phone.
This fix obviously sucks, and a new fix has recently been released by a veritable android-demigod around the Galaxy.
HERE IS A THREAD ABOUT NO SLEEP ON i7500 GALAXY;
(ok, some stupid rule says i can't post links - can a mod help me out?)
HERE IS THE FIX FOR THAT PARTICULAR BUG;
(ok, some stupid rule says i can't post links - can a mod help me out?)
LINKS ARE IN POST #5 - THANKS TO ONDOTEAM (would still be nice to get them in this original post though)
Now, from my experience, no sleep behave exactly the same way on the x10 as it does on the Galaxy;
1) I turn of all location services, and my battery life at least doubles.
2) After said turning off of services, 'spare parts' no longer says 100% running time under battery usage - in fact it can be as low as 10%.
These two factors are identical to my experience with Galaxy. SO; is there any way drakaz's fix can be applied to our X10's? It seems to me that the files he mods are standard Android system files, not sony/samsung specific.
Now i am no developer, so i dont know it this is possible - the first question that comes to mind for me is "do we need root access, or can this be done through developer tools using the android SDK?"
Can anyone help shed anymore light on this?
Seems to work for me. I disabled all location services. Spare Parts went down from 100% to 7.6%.
I'll just have to enable GPS when I need to use it..
Awesome! Glad to hear it has helped.
Let's keep testing this guys - if it does show up to be a big cause, then perhaps the devs around this place can help is figure out a patch for Drakas' mod to make it work with our x10's!

No sleep is easy to fix, took me a while to figure it...
Turn your screen brightness from manual to auto, spare parts will now start showing proper running stats, no more 100% running.
The screen is a little dark in auto but it will cure the 100% running.
GPS and location services etc make no difference to my X10i, I am running the 1.6 version unbranded UK handset, the only thing to stop mine running 100% is to put the screen on Auto.

My phone came out of the box with auto-brightness and i never changed that option, yet i still had no sleep.
Drakaz has done some fairly deep digging and is next to certain that it is an artefact of the geolocation bug discussed in the thread in which the problem was fixed.

Although I'd half assumed that they were referring to the total "up-time" figure which you can see at the bottom of the "about phone"; "Status" screen.. But perhaps not.?
Spare Parts is a standalone Program ...

Spare parts is indeed available from the market - it is a much more powerful tool for indicating battery usage than the regular android methods. The galaxy stared on 1.5 which had NO indicator of battery usage statistics at all, so we all learned about spare parts very fast.
Perhaps that is why no x10 users have realised about the potential no sleep bug; because so far only the android usage indicators have been used?...
Anyway, hopefully this can help us all understand the way our phones are working better together

14% it's mine value for running time, not 100%. By the way thats 30 minutes of 210 in total :S
I'm also experiencing "No sleep bug" after i used GPS. I use Battery Graph to plot my power consumption and after I use GPS, I can clearly see that power consumption is high even if i turn the phone in plane mode.
In addition SE widget, used to turn on/off GPS, seems to not work very well for me. So, to fix the bug, i manually disable GPS in parameter menu and restart my phone. After that power consumption is hardly null (20% in 8h with MP3 on almost all the time).

Do you have 3G always on?
My phone has no trouble sleeping.
Gps hasn't really been an issue but I keep it off when not needed.
Here's my solid settings:
1) No auto sync
2) No moxier
3) Gps off
4) Restart after using wireless
As long as it's like this my phone lasts 2 days easily

I have been playing with mine for a month to work out what caused mine to not go into sleep, I keep GPS wifi etc on 24/7 but in spare parts I was running 100%, after numerous reinstalls and removing everything i chanced on turning on auto screen brightness, now when i unplug my x10 the running sits at the correct level.
No Geolocation bug here
I have this problem with 100% on and off. Sometimes when I check its under control (~10%), other times its at 100%. I have GPS off, no WiFi, auto brightness... don't know why it sometimes just gets stuck at 100% :/

Phone Keeps FREEZING!!! What the heck Samsung?!!!

My galaxy S freezes out of the blue, and i can't even turn it off. Sometimes i look to check the time, and noticed the phone is turned off. Both problems are only corrected by taking out the battery, and putting it back in...and then waiting for it to happen again!
Is this a software issue that 2.2 will fix? Should I exchange for a new one, or will all of them have the same problems, if bought from the same place? (Best Buy in Vancouver Canada)
either your battery is not good, or your got a defective phone
the new SGS out of the box works smooth
what is your firmware version?
type in
*#*#1234#*#*
Sounds like a bad phone. I got mine from one touch in delta and it has been perfect. Return asap and get yourself a working unit.

Thought you meant lag. Mine lags a lot (stock firmware) and sometimes "freezing" seems the word.
But no, that's not it. Perhaps you can try a hard reset and check your sdcard too, something isn't ok.
I'm actually experiencing the same issue. My phone goes black and seems to be happening more in low wireless connection areas. Like in a mall. With the the *# code I get I9000UGJG9.
if you have LAG issues, install the one click lag fix in the development area
problem solved
Its not LAG issues it a complete freeze issue. My phone goes black like standby mode and will not come out of it. The only fix is a battery pull or holding the power button for 6 seconds. The same issue as the op.

you do not lose the Apps
once you log back into your Gmail account in your new phone, when you go into Android Market, they will remain in the Download section
those apps are saved in your Gmail account, not in the phone.
that's the cool thing about the android phones
so if you ever switch to say an HTC Android, or a Nokia Android, you can still re-install those apps (assuming they are compatible)
Oh sweet I wasn't aware of that. I sold a couple of the Galaxy S and I'm the only one with this issue as of yet. Hopefully it isn't a common one. I've been trying my best to convert Iphone buyers in most cases when I'm sold out to get this phone I just hope it delievers for my customers and they won't have the same issue as me.

you do know you don't just slide
you have to move the entire picture of the "slide" out of the phone frame for it to unlock
if you say only slide it partially, it will just bounce back and remain locked.
if you have thick fingers it wont work properly
you might be better off using the 3rd party unlock screens, specially the kinds that needs no sliding.
i have that issues nowadays too. randomly "freezes" on the black screen, i can call through my phone (ringing) but there's no notification / vibration or anything or sorts.
the only way is to reboot the phone and it'll randomly happen again after some time >.> and the call that i've just missed isn't showing on the call-log either.
i hope it gets better overtime or i'll just have to reflash!
ps. was fine before i tweaked my cpu settings in sleep mode, you might wanna disable that if you're using it.
Mine has the same problem and by the looks of things a lot of people have this issue. I called customer support and after sometime the rep admitted this and said it will be fixed in next build however I doubt that
Then there are probably lots of diff units out there. The phone shouldn't freeze unless you are using a beta/alpha firmware (pretty unlikely - i've tested more than 10 different firmwares without a freeze), or set the core clock of the cpu to a higher & unstable frequency (OC). people claim that their phone can do 1.2ghz - that's nice, but each chip has a different capability.

/INIT process Desire HD lag problems...SOLVED ! See post 1

I'd like to know if anyone is having the same lag problems as I am getting from time to time..
The lag happens for no reason and comes at different times while doing different things.
I downloaded Watchtower from the Android Market to monitor what was happening. When the phone is running fast the /INIT process is showing as 0%..as soon as the lag starts to happen I check Watchtower again and the /INIT process is at anywhere from 70% to 100% CPU usage.
I dont use an app killer but I donwloaded one to try and see if it would correct the problem, it doesn't. The only way to solve the lag is to Restart the phone, then its fine for the rest of the day, sometimes two days but it always comes back.
I sold my SGS because of the lag issue and now it seems I have it with the DHD..
I did google this and I found that it maybe something to do with android itself..looks like /INIT is an android process..
If you notice your DHD lagging then download Watchtower and I'd bet you will see the /INIT process killing your phone..
------------------------------------------------------------------------------------------------------------------------------------
EDIT - A fix has been found to stop the /Init process lagging the phone.
On your phone go to..
Menu/settings/applications/development/now turn on Usb debugging..
This seems to keep the / init process at 0% CPU usage, it also works when the /INIT problem starts, turning USB debugging on will make the /INIT process drop back to 0%, very nice to see.
Ive contacted the Dev to find out if he can tell us why this method has fixed the problem.
Still need an update from Htc but at least we can use our phones again..
There doesn't seem to be any negative effects from turning this option on, the only thing to note is turning it off to connect to your pc could bring the /init process back and lag your phone. You can download Android Manager from the market for free which will allow you to transfer data from your pc using Wi-Fi, using this app you can keep the USB Debugging on.
-------------------------------------------------------------------------------------------------------------------------------------
EDIT 2 - It looks like you can connect to the pc via USB cable with the debugging turned on without problems, the only difference is that it will try and install additional drivers...because of the debugging mode..
Im using windows 7 and the ABD driver wont install...you need to download Htc Sync on your pc which downloads the ABD driver !!
We should also watch the battery as this may actually increase battery life...
-------------------------------------------------------------------------------------------------------------------------------------
EDIT 3 - Not one single person has come back to me and said that the /INIT problem has returned after this fix...lets hope it stays that way.. 10/11/10
---------------------------------------------------------------------------------------------------------------------------------------------------
EDIT 4 - A lot of people including myself have found that this fix improves their battery life quite a bit.
-----------------------------------------------------------------------------
Last EDIT before thread is locked just for reference and to help people !!!
For people that have the com.htc.bgp process that loads the CPU it stays at 80-90% all the time, and i have autosync on, if you stop auto sync the process goes out....
So here is the final fix in the link below (post 7)

An app killer doesn't solve the problem and Im unsure how many people are having this problem, to my understanding its not many...that's why I started this thread to try and find out.
I wouldn't worry yet...
I will make a video when it happens again...it may take a few days to come back....but it always does...a video added to this thread would be most useful...just have to wait till it rears its ugly head again.
So it seems that /init is a core process regarding the initialisation of the Android system and userspace hence the fact it cannot be killed using OSMonitor. It is always the first process that runs on Linux systems after boot and acts as a parent process which itself initialises then processes needed to get the OS going.
Here is a description of the Android Init Process from elinux,
'init'
A key component of the Android bootup sequence is the program 'init', which is a specialized program for initializing elements of the Android system. Unlike other Linux systems (embedded or otherwise), Android uses its own initialization program. (Linux desktop systems have historically used some combination of /etc/inittab and sysV init levels - e.g. /etc/rc.d/init.d with symlinks in /etc/rc.d/rc.[2345]). Some embedded Linux systems use simplified forms of these -- such as the init program included in busybox, which processes a limited form of /etc/inittab, or a direct invocation of a shell script or small program to do fixed initialization steps.
The init program processes two files, executing the commands it finds in them, called 'init.rc' and 'init.<machine_name>.rc', where <machine_name> is the name of the hardware that Android is running on. (Usually, this is a code word. The name of the HTC1 hardware for the ADP1 is 'trout', and the name of the emulator is 'goldfish'.
the 'init.rc' file is intended to provide the generic initialization instructions, while the 'init.<machine_name>.rc' file is intended to provide the machine-specific initialization instructions.
The Bug
The /init bug has presented itself on numerous handsets including the HTC Desire, Nexus One and Droid X models. It seems to be specific to Android 2.2 and reports the same symptoms on all handsets. Primarily this is due the 99% CPU usage causing system slowdown and left unchecked, high battery usage. It is not specific to HTC Sense ROMs as it also presents itself on stock releases. The only solution so far is a reboot. Hard Reboots and altering system settings seem to have no effect on the reproduction of this bug.
I can only speculate to what is causing the issue and hopefully a Dev can shed some more light.
Logically it seems as though a 'rogue' process is triggering /init to resume its primary function in regards to checking filesystems and attempting to spawn other system process. Due to some form of miscommunication between the processes in question, /init continues to perform these post boot tasks in a constant loop.
Think of it like this, if you try perform tasks straight after boot, the phone is unresponsive while the SD is mounted/checked and all other processes are fired up. The /init process is responsible for these tasks. If it were to loop, you would experience the symptoms we are having.
I found this on Wikipedia:
After /init has spawned all of the processes specified, init goes dormant, and waits for one of three events to happen:- processes it started to end or die, a power failure signal[clarification needed], or a request via /sbin/telinit to further change the runlevel.
So our trigger should hopefully be narrowed down to these three events.
Regarding what I posted before, the connection between sync and the bug has proven itself to be a false one.
I've also noticed that sometimes the bug can be present, however there is little impact on the responsiveness of the OS. It can seem as though everything is ok yet the CPU load can be extremely high, resulting in poor battery performance.
Anyway, hopefully more people can contribute to this thread so we can build up a better picture of what is going on. I will also try and grab a Logcat and ask anyone else near their PC when it happens to do the same.
There is a thread here which has users complaining of the same problems, yet no solutions are presented. Hopefully we can make a bit more noise and get some definitive answers.
Regards.
Hey guys some great feedback here, as with my link on starting this thread the /INIT is an android 2.2 process, auto sync on/off doesn't solve the problem neither does a hard reset, taking the battery out ect...
The guy in the link says his method worked for him, can't say the same for myself, I have a feeling his problem will be back...but if it did fix it for him then thats great, just cant say the same for me
http://forum.xda-developers.com/show...3&postcount=42
I have gone 5 days without the problem coming back and then Oh no its back, sometimes it happens twice a day, all the above doesn't fix this problem im afraid from what I have experience anyway.
The /INIT process is only 132k, something so small causes the phone to be basically unusable....very frustrating.
The 1.32.405.6 update also doesn't solve this problem, I updated yesterday and 10 min later I had the dreaded /INIT problem...
The so called "turn off fast boot doesn't fix the problem either, I have had the /INIT lag problem with it switched on and off...
What I find to be the most strangest thing is that if this is indeed an android process which it most likely is then why doesn't every DHD phone have this lag from time to time???.....why only certain phones??..
I haven't had the problem since yesterday (around 12 midday), when it occurs again I will be posting a video as requested...
The mystery continues.......There is NO solution as yet that fixes this problem.
Thanks to Lynxboy, your posts give some good information.
I wonder if this has any relevance to the problem from a linux based PC..
It seems that /INIT uses the same Process ID - 1 (found from using watchtower)

You purchased it from ebay, but did you buy it from a shop or from an individual (second hand)?
If you got it from an ebay shop they should give you a receipt. If it was from an individual, he should give you his original receipt (that's when the warranty started).
Anyway, the phone has a 2 years warranty, so you are covered for the next 2 years minus 1 or 2 weeks. And the paypal transaction is a valid payment receipt (it can be verified directly with paypal); so even without the receipt from the first owner HTC should cover you since the phone can't be 2 years old.
Get in touch with HTC directly, they should replace it. But the tricky part is that the problem must happen when they check it out, for this reason I would also make a video of the problem the next time it happens and send it to them by email so they can keep it on file with your RMA.

Thanks for the advice, Im going to contact the seller, he had it on upgrade and shipped it to me the following day..he seemed a nice guy so It should be ok...Now its just a matter of waiting for MR INIT to show up haha....wonder if he wears a hoodie LOL

I'm not wrong because I see it with my own eyes. Even my DHD had the same problems as described. After the update no more /INIT at 90% and it keeps running smooth now.

What?? Why do you think I made this thread...to help myself and others...as we do at XDA....the update doesn't fix the problem....just because yours hasn't lagged since the update doesn't mean its fixed....I've gone 5 days with no lag and it came back...like yours probably will.
Ridiculous....
EDIT- You can't post a statement that the problem as been fixed when numerous people have done the update and still experienced the /INIT problem...how can it be fixed??...and since the update only came out yesterday you have no way of knowing this for sure... its way to early to say that.. Try reading through posts in the forum and gather some information next time.... the update was for the youtube fix, we're not even sure that HTC were aware of the problem at the time.
Hi guys,
Just finished work and have caught up with the thread since I last posted and wanted to clarify a few things. I would also ask any new readers to find my previous post which covers much of the nature of the /init process.
The problem is solely software based. The hardware is NOT at fault!
The /init process is the parent process of Android/Linux, hence the PID 1 in OS Monitor. Imagine it as the ignition system in your car. You need to turn the ignition to fire up the other systems and that technically is the role /init takes.
It is not a rogue process in itself. It cannot be killed or closed via a task manager.
The latest update was not a fix nor does it resolve the issue.
The bug IS a Froyo bug and affects numerous devices not just the DHD although it is not present in all Froyo ROMs.
It is possible the memory management is to blame however I have run many Froyo based ROMs from FRF55 and not experienced it before; they all use the same memory management.
The three triggers for /init to awaken after its boot tasks are completed are specified in my previous post. These are the most likely causes for our issue and are in my mind triggered by some rogue process interactions.
A logcat will only really be useful if it captures the event taking place. A logcat taken when the /init process has started will report back specifically that.
Just because you haven't experienced the bug in 2days doesn't mean you are bug free, nor is there a bad batch of phones as this would indicate a hardware issue.
Continuing this thought, it is possible if you are on a branded operator ROM you may be bug free.
The /init bug is extremely annoying.
Regards.
Yes off topic...
Im asking the mod to still keep this a sticky but to lock the thread as there is really nothing left to discuss and its just here for people that are still having the /init problem as a reference...
EDIT - Thread being locked soon so....
Agian thanks to all xda community !!
Is this stickie needed anymore? Has this been corrected by any software update?
I've had this problem since the day I got the phone (December 2010) and got it again today. Once I see the obvious lag of everything, I just restart.
If it can help...
I have noticed this phenomenon the first time just after installing 2 things in my DHD :
- creating the HTCSense account (and keeping it synchronized one a day)
- installing the HTC plugin for Picasa Web Albums in the Album application.
Maybe coïncidence, maybe not.
I have disabled all HTC Sense stuff I can see. It always happens when performing some action, like opening a new app. It seems to occur so randomly, it happened again the day after my last post, but has been fine since then.
Problems with calendar after removing cache and program data.
I had major problems with com.htc.bgp using up to about 90% of my processor from time to time. When I searched the forums I found this thread.
I tried what is stated in the top post and went ahead and cleared the calendar data and the gmaill data. This is all fine, I don't seem to get any more warnings about com.htc.bgp reaching the 90% mark. One slight problem that occured though is that now when I'm syncing my calendar back to what it was, it either does not search or does not find all the other calendars that I have. The list is just totally empty. Strange as it is, It does find and sync with the default [email protected] Gmail's working fine and syncing properly though.
Since I rely on the calendar I really need this to be fixed as soon as possible.
I don't want to put words in your mouths, but I figured I might need to factory reset the phone. No biggie, but a time consumer, since I need to recustomize everything again (not rooted, not titanium).
Are there any ways of luring the calendar back on track. Jumpstarting it without a factory reset?
Thanks in advance.
Henrik
So apparently all it needed was a full night of syncing, because now it works again.
It seems though that I got rid of the annoying com.HTC.bgp that drained my processor.

[Q] Is the 'suspend process' issue truly a mystery?

I have searched through XDA and read all the threads regarding the 'suspend process' issue. The specific issue is outlined in Issue # 11126 on the Google Code/Android project home...
http://code.google.com/p/android/issues/detail?id=11126
I am trying to get to the bottom of this, as best as possible. For all intents and purposes, this really appears to be a mystery. Ultimately, it appears as though there is (currently) absolutely no specific reason a to why 'suspend' runs wild until the device is rebooted.
My question is (I know we can all only speculate):
Is there any chance that this could be Google account-specific?
The reason I ask is, I've been doing some "testing," just to try and make sense of this for myself. Here is what I've done/come across thus far...
- My fiancee's first MT4G was a black one manufactured in Taiwan. It had the inferior LCD-SH-C2 screen. Her battery was draining VERY quickly - i.e. before noon, without using the phone for much else other than texting.
- I enabled USB Debugging for her, to "rule out" the init process issue.
- Even though she only had Handcent, Facebook and Angry Birds installed, I removed all of them, leaving only Watchdog.
- I factory reset her phone, twice.
- For all of the above, the device was not rooted. I have since rooted her phone via the steps in this thread.
I'm in the process of creating a new Gmail account for her, exporting ONLY her contacts and then using that account for her new MT4G (Plum) that's scheduled to arrive today. I'm actually thinking of NOT using her new Gmail account at first though, so I can use her original Google account on this new, clean device and see if the suspend issue persists.
I might just be wasting my time, but I enjoy doing this and I don't think it's a complete waste to try and find SOME constant here. Am I nuts for thinking it's tied to the Google account? The Google account seems to be a black box of sorts. There is more than just contacts, apps and settings, yet there is no "window" into everything else that comes down - e.g. I can't log in to Gmail and "configure" it to not restore her wallpaper or WiFi settings. So that's why I say it's a black box of sorts, since it's doing more in the background than we have control over.
Nothing is truly random, at least not in the context of Android and the hardware affected. There has to be some reason why users of various devices, either do or do not experience this issue. Whether it's a specific action or the something that differs between one person's action vs. another person's, there has to be SOMETHING that's triggering this on her device, yet never triggers it on mine. I guess I'm just trying to flush everything out and hope that discussing it will help rule out/rule specific variables.
Let me know what you find. This is driving me crazy! I charge my phone at night, so when I head to work it's at 100%. By the time I'm heading home (4-430pm)... the phone is around 15% battery.
Watchdog tells me suspend ranges from 5%-49% at any given time. I've never had suspend drop below 5% except on fresh reboot. I've noticed, though, after a reboot that the suspend process will slowly work its way back up to using lots of CPU cycles (it starts at, say, .2%, then 10 minutes later its 3%... 30 minutes later its 5%... an hour later its 9%). Battery just gets hotter and hotter due to this.
I'll be checking back to see what you find! Thanks!

According to XDA and Issue #11126, you're not alone.
What's really bugging me is that neither my first MT4G, nor its 1st replacement or its 2nd replacement, have ever done this. My fiancee's first phone did this. She is now using my 2nd replacement while she waits for hers to arrive (today). So a device that never exhibited this issue, over the course of at least a week of normal-for-me use, started exhibiting this issue for my fiancee maybe a day or so after using the phone.
I thought I had "solved" it when I didn't see it crop up the first day she used my replacement phone. She was quick to let me know I was incorrect.
So I've got serious pressure here - all of my MT4G's haven't exhibited the out of control 'suspend process' issue while I was using the devices, but with her, it does. <queue the jokes>
We own our own business, so we're in the same room all day long while we use our phones. I was the first to tell her, "it's something you're doing." I'm only repeating myself by saying that I blamed it on an app she installed or something she "did" to cause it. After factory resetting, what...2, 3 times...I'm starting to forget; after checking the apps that are installed (and removing all of them); after verifying every setting from USB Debugging, screen brightness, account sync, etc. I seem to at least be able to say, "every single setting, shortcut, widget, app or usage pattern, does not produce the issue on any device I have used with my Google account, whereas it does with my fiancee."
That's the most difficult part to get absolute - the usage pattern. She's doing such basic things though, but I know that even the slightest of difference can produce different results.
I will most certainly report my results, futile or not.
The only common denominator I've noticed so far is that it only affects Sense UI devices.

That seems to be the constant, to a degree. I'm seeing people state that they're having this issue on anything from the Samsung Galaxy S (i9000) to a Nexus running Cyanogen 6.1. That's people stating it though, so I'm not sure if they're actually experiencing the same issue or not.
I am biting my tongue, but I think I found another common denominator...I am going to post back in a coupla days once I've seen it last for this entire week.
hi,
i'm running cyanogenmod 6.1 on a desire hd and have been experiencing the suspend process problem exactly as described in this thread a nubmer of times now over the last week. so its definately not limited to devices running sense.
the only circumstances this behavior hasnt shown is when running 2g only with all other sorts of communications and sync off

Yeah, it didn't seem 100% related to devices running Sense, so thanks for posting back to this.
My fiancee was experiencing this across her first two MT4G devices and has yet to experience the issue on her third and final MT4G. I want to see it run the rest of the week though before I share, but the issue did pop-up for her pretty much within 24-48 hours on her first two MT4G's.
Shlongwoodian: I have been following your posts as the "suspend" process has been affecting me since I received my phone the first day available. However, I am reluctant to send for a replacement as all else is great on the unit I have and there seems no gaurantee that a new phone fixes this issue.
I have tried Tmo and HTC and both seem clueless; therefore, I appreciate your research and look forward to any "fix" short of waiting for Gingerbread.
Anyone have any wisdom to pass on? This issue is driving me crazy! I've noticed it most on my black MT4G (w/the good screen) after browsing the web, youtube or using the media player. My wife's red MT4G (w/the inferior screen) has had no issues and her battery is amazing! The first day she got her phone her battery lasted 24 hours without even conditioning it! Granted she doesn't use it like I do mine, but it is still a huge difference. When this issue comes up on mine, I'm dead within 3-4 hours. I have Watchdog set so when it alerts me I just soft reset. That clears it up until it decides to come back at random intervals. It usually doesn't come back until I open the browser, etc. With as much as I use my phone (I am constantly on the road), it becomes a major pain to have to constantly monitor battery life. Any help is greatly appreciated!!!
Man, I am sorry to report that I gots nothin'. Ok, here was my original theory...
I was speculating that "something" inside the Google/Gmail account was the cause. My reasoning being, essentially, your info is stored in a database. When you get an Android device, that online database is synced locally with the phone's database. We each have different databases and there is more than just your apps, Market links, contacts, etc. I never exhibited the /suspend issue on phones that she experienced the /suspend issue on. I figured it was database-specific.
If a table contains a value, or rather, does not contain a specific value (or if columns are missing, etc.), it can cause an application to respond in a negative way. Sometimes, this causes an error to bubble up in an application. Other times, it doesn't. In my experience, I've seen much more subtle issues in databases, that don't cause errors or a crash, but instead just cause "undesirable results."
When my fiancee got her final, good replacement Plum Glacier, we started with a completely new Google account. We thought we nailed it, when a handful of days passed without seeing /suspend get out of control, leading to Android System and/or OS sucking down battery life. I think it was nearly a week into it and one day while she was out, she realized she lost battery life really quickly - i.e. left the house with 90% and by the time she got to the store, shopped for a bit and looked, her phone was down to like 30-40%. She knows how to check for /suspend and it was, of course, back.
It's still not something that can be completely ruled out, since it's not a very air-tight test. There could be something about my Google account (which I've had pretty much since Gmail beta was available) that's keeping me (and others like me) from getting it or that idea could be crap.
For some reason, I have never, ever seen this happen on my Glacier(s) running stock 2.2.1. Phones that I never saw the issue on, she saw the issue on. There is so much speculation around it, but it just seems like "some people" don't experience it and "some people" do. It's all over different devices, different skill levels, etc. No apps, same apps, whatever and it happens to some but not others.
Sorry to get anyone's hopes up. I'll keep looking for differences/similarities though and if I find anything at all I'll - or if anyone else finds anything, no matter how ridiculous it sounds (yes, we've tested the 'rock' and it doesn't appear to suffer from the /suspend issue) - post it here.
Thanks for trying! It was a good theory. So . . . now what? Is there any way to get this ranked higher with Google, HTC, etc. to get more people working on it? It is really driving me nuts! It mainly happens after I use the web browser, then put the phone on standby for some reason. I can't even use the browser any more without needing to reboot it to save battery life. There is another thread, but specifically for the Evo and I think one for the Nexus one, all with the same problem. What if a new thread were started that is not device specific? That way we can get more people to star it and maybe Google or whoever will pay more attention to it! I would hate to think that we are stuck with this problem until when and if we get upgraded to 2.3. I would suggest rooting and flashing a new ROM, but even those with custom ROM's are having the same problem, so that's not going to help. Thoughts???

It truly is a mystery to this day. I've seen people say, "it happened right after I installed Handcent" or "it happens as soon as I do..." No one has come up with any concrete evidence thus far.
My fiancee has Handcent, I have Handcent. I used Handcent heavily, never had an issue. She stopped using Handcent - still has the issue. We've gotten so granular in our troubleshooting, we're literally tracking every step. LOL i.e. I pressed the trackpad to wake the phone, once; I unlocked the phone, I swiped my thumb once to view my Watchdog Widget on the screen to the left of my homescreen, etc., etc., etc.
So, for now, we just wait? My phone (and all previous phones) have been just fine. My fiancee however...yeah, I'm trying to find a fix pretty quickly.
One common theme that I've seen with this issue is that it only happens after I put the phone to sleep. I have never seen it crop up while actually using the phone. Maybe we're going about it the wrong way in trying to identify an app, etc that's causing the problem... perhaps it is simply the code involved in putting the phone to sleep and that's why there hasn't been any consistency with what one does to make it appear. In your experience, have you ever seen or heard of it showing up while the phone is being used? Perhaps it's just on mine that it works that way, but I thought it was worth mentioning. I know nothing about code or how android works so please forgive the noob comment if this is an obvious one. Merry Christmas!
I've got this problem big time. Returned my first phone because I thought it was the phone. First few days were good but lately its back and as bad as ever. First thoughts were angry birds twitter or wifi but I have no idea. If I can't figure this out I might have to sell this phone.
I will try to post some more thoughts. I think you're onto some good ideas here.
Sent from my HTC Glacier using XDA App
(Re-posting from the developer's Google blog where others are following this issue): Interesting about using the phone without a Google account. Not sure if this is relevant or not, but I've noticed something else with consistency. Granted I wasn't able to document the behavior through system panel at the time, but this has consistently happened. When suspend goes crazy, I can get it to stop simply by charging the phone! Even if I charge the phone for a few seconds, then unplug, it stays dormant without having to reboot. Noob speaking here but perhaps the part of android that actually logs the battery usage is suspending when the phone goes to sleep? When it us charging, this log is reset and clears the process from running. If this is even possible, then could someone write an app that clears this system log? Maybe by mimicking what happens when the phone is charging, we can at least temporarily clear the issue without the need tovl reboot? Again, I know nothing about all this so sorry if this is all irrelevant. Just sharing what I've noticed to be consistent. Thoughts??
Also, I saw on another xda blog (http://forum.xda-developers.com/showthread.php?t=870557&page=2) that someone linked this issue to a corrupt photo on the sd card. After formatting the card and restoring some files, says the issue has not returned!

I wonder if you're on to something with the SD card. I've been thinking I haven't seen the suspend issue return on my phone in quite a while. I just realized that the only thing I've really changed is installed a new 16 gb SD card. Since then, no suspend process problems. For those who are having the problem still, I wonder if removing or formatting their cards would show any improvement? Worth a shot if at least to eliminate another possible factor.

That's cool that this thread is flushing out other ideas and possible variables. I like the idea of connecting it to the charger for a couple of seconds, but my fiancee is so used to just rebooting her phone each morning and sometimes again by mid-day, that it's easier for her to do just that.

I like the microSD Card notion. This is such a weird issue, that it's so easily associated with other items - e.g. applications, usage patterns, etc. This seems feasible though, but the only way to know for sure is to reproduce it. My fiancee experiences the suspend issue daily, if she doesn't reboot regularly. So, I should be able to take her microSD card and use it in my phone and get the suspend issue. I don't want to 'muddy' up by swapping microSD cards, so I'll try reformatting her card and see if that makes any difference. She usually sees the issue within 24-48 hours of a fresh boot, so it shouldn't be long before we see if that fixes it or not. I can check the card for errors, etc. as well.

I'll be upgrading to a 16 GB Class 10 soon, so I can give her my Samsung if need be. I'd really like to see if this is it though. It would explain the "some people get it and some people don't" pattern.
I also noticed that the minute I plug the phone in the problem goes away. Not sure why, just confirming it happens to me too. I also should note that when I returned my phone, they popped my old SD card into my new phone. So if there is an SD card issue with a corupt file/photo that could be something as well. I wonder woody if your girlfriends phone has had the same SD card after how many times did you say you traded it in? BTW, a side note, how did you exchange it so many times? After I took mine back to the store on day 14 they told me I wasn't able to exchange it again.
I do have a 16GB SD card but just haven't had time to install it. Wanted to double check which things I need on the new one from the old one, but it might be a good way to test this issue. Let me know some ideas before I swap the cards and maybe I can help test this.
Also, one more thing, what is the app you're using to log stuff? I'm just using Watchdog Lite right now.
I've got to figure this out or this is a dealbreaker for me. I have waited 3 years to upgrade phones, first time on Android, really wanted iPhone but wanted to stick with month to month from TMob. If this continues I think I will move to Windows Phone 7 or iPhone if I have to, but I really like this phone when the battery is not draining like a leech.
Thanks.
werk,
Just wondering what process you went through when you upgraded SD cards. Did you copy any files over to the new one or just start blank?
Thanks.

Just straight copied the existing files over from the old card to new one (new one in phone connected via USB, old card in SD adapter in my laptops SD card slot). I think some Angry Birds files didn't make it due to long paths, but reinstalled it and no problems since then.

I've got the freezing eMMc bug - why does wakelock fix what should be a hardware bug?

My note 4 has developed the eMMc bug - randomly freezing all the time. Well, half-freezing - the status bar still updates, enough for Cool Tool Pro to show me that the CPU is at 100%. But I can't do anything with the phone. Sometimes it freezes when I try to press the power button to turn the phone on. I have to do that stupid battery thing where you have to take the battery out and leave it out for 2-3 minutes to reboot it.
And worst of all, using the partial wakelock that everyone else is suggesting, fixes it, which confirms I am having the same bug. But that doesn't make any sense. If it's a result of failing eMMc hardware and bad sectors, why does preventing the CPU from falling asleep fix this?
Just have a look at wakelock app page, it's all explained there

I have the same question.
Not much info there unless you scan the comments section.

all of us that are having (or had) this problem must know that these are the first symptoms of the emmc bug that massively have stroke on Note 4, more than any other Samsung phone.
As I was one of them , i would suggest this app rather than the darken's one:

but keep in mind that, this is a hardware issue, which I am afraid will continue and eventually will leave you no other option, but to change your motherboard.
take a look here and be prepared, although I wish its not he case with you guys
